Unable to pay for the renewing subscription

I purchased AVG Antivirus last year, atleast I believe so, but it came in a pack with TuneUp. So I have been using both of them yet it says I was subscribed to TuneUp and it is Awaiting Payment. I do not see the subscription on my account so I believe I had used the wrong email address when purchasing. It would go through but I believe my payment method has been cancelled and I do not know how to unsubscribe so I can repurchase it or what, please tell me what I should do.

Hello Illyana,

We are glad to look into this and help you.
We have sent you an email informing about the AVG products and please revert to that email for further queries.
Thank you.
